Abstract (en)

[origin: EP1022587A1] An anti-reflection film comprises a high refractive index layer having a refractive index of 1.65-2.40, and a low refractive index layer having a refractive index of 1.20-1.55. Another anti-reflection film comprises only a low refractive index layer having a refractive index of 1.20-1.55. In the invention, the first improvement resides in a high refractive index layer composed of inorganic fine particles having a mean particle size of 1-200 nm in an amount of 5-65 vol.% and a crosslinked anionic polymer in an amount of 35 to 95 vol.%. The second improvement resides in a low refractive index layer composed of inorganic fine particles having a mean particle size of 0.5-200 nm in an amount of 50-95 wt.% and a polymer in an amount of 5-50 wt.%, and two or more of those particles are piled up to form micro voidsby the adjacent particles. <IMAGE>
